目的针对壳体结构模型进行减振设计，使其能经受宽带随机振动环境考核。
Objective In order to ensure that a shell structure can stand up the test of wideband random vibration environment, a vibration isolation design method is developed.
本文在某支撑座结构模型宽带随机振动实验的基础上，研究了如何监测连接螺钉组松动故障程度的问题。
Based on the broad-band random vibration test on a clamping support in missiles, this paper investigates the problems on evaluating the attachment bolt looseness in the structure.
结构的宽带随机振动理论是随机振动理论中一个引起兴趣的领域。这种随机振动模态数量很大，从而呈现简单的渐近趋向。
Wide band random vibration of structures is an interesting area in the theory of random vibration in which the number of responding modes is so large that some asymptotic behaviour may be observed.
